This inhabitant, of the dry Chaco forests in Southeastern South America, has developed some decidedly unfrog-like behaviors. Instead of laying its eggs in water, it builds a nest above it, laying eggs on a leaf, which it folds around them. There the tadpoles hatch, then fall into the stream below. It smears its body with wax secreted out of its own skin, using complicated maneuvers of its hind legs. Its unusually expressive appearance has made it popular in zoos, and it is now captive-bred in increasing numbers.
